    NEW
GENERATION BIOFUELS HOLDINGS, INC.

    WARRANT

    TO
PURCHASE COMMON STOCK

     

    Issue
Date: December   
, 2009 (the “Issue
Date”)

    


    THIS WARRANT IS TO CERTIFY
THAT, the registered holder hereof or its permitted assigns (the “Holder”), is
entitled, subject to the terms set forth below, to purchase from New Generation
Biofuels Holdings, Inc., a Florida corporation (the “Company”), ________
shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at
$0.90 per share, as adjusted from time to time pursuant to Section 2 hereof (the
“Exercise
Price”). Subject to the terms and conditions hereof, this Warrant may be
exercised by the Holder at any time after the six month anniversary of the Issue
Date but prior to the fifth anniversary of the Issue Date (as further defined
herein, the “Expiration Date”), in
whole or in part.

    


    Section
1.  Exercise of Warrant.

     

    (a)  Mechanics of
Exercise.  (i)  This Warrant may be exercised by the
Holder, in whole or in part, by delivering to the Company at its office
identified in Section
14 hereof (i) a written notice of exercise, in the form attached hereto
as Exhibit A
(the “Notice of
Exercise”), including the number of Warrant Shares to be delivered
pursuant to such exercise, (ii) this Warrant and (iii) (A) payment to the
Company of an amount equal to the Exercise Price multiplied by the number of
Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise
Price”) in cash or wire transfer of immediately available funds or (B) by
notifying the Company that this Warrant is being exercised pursuant to a
Cashless Exercise (as defined in Section 1(c)).

     

    (ii)  The Holder shall not
be required to surrender this Warrant in order to effect an exercise hereunder,
provided that this Warrant is surrendered to the Company by the second Business
Day following the date on which the Company has received each of the Notice of
Exercise and the Aggregate Exercise Price (the “Exercise Delivery
Documents”).  On or before the first Business Day following the
date on which the Company has received the Exercise Delivery Documents, the
Company shall transmit by facsimile an acknowledgment of confirmation of receipt
of the Exercise Delivery Documents to the Holder and the Company’s transfer
agent (the “Transfer
Agent”).  The Company shall deliver any objection to the
Exercise Delivery Documents on or before the second Business Day following the
date on which the Company has received all of the Exercise Delivery
Documents.  In the event of any discrepancy or dispute, the records of
the Company shall be controlling and determinative in the absence of manifest
error.  On or before the third Business Day following the date on
which the Company has received all of the Exercise Delivery Documents and after
the Company has received this Warrant (the “Share Delivery
Date”), the Company shall, (A) provided that the Transfer Agent is
participating in The Depository Trust Company (“DTC”) Fast Automated
Securities Transfer Program (the “FAST Program”) and so
long as the certificates therefor are not required to bear a legend regarding
restriction on transferability, upon the request of the Holder, credit such
aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with
DTC through its Deposit Withdrawal Agent Commission system, or (B) if the
Transfer Agent is not participating in the FAST Program or if the certificates
are required to bear a legend regarding restriction on transferability, issue
and dispatch by overnight courier to the address as specified in the Notice of
Exercise, a certificate, registered in the Company’s share register in the name
of the Holder or its designee, for the number of shares of Common Stock to which
the Holder is entitled pursuant to such exercise.  Upon delivery of
the Exercise Delivery Documents and surrender of this Warrant, the Holder shall
be deemed for all corporate purposes to have become the holder of record of the
Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date such Warrant Shares are credited to the Holder’s DTC
account or the date of delivery of the certificates evidencing such Warrant
Shares, as the case may be.

    (iii)  If this Warrant is
submitted in connection with any exercise pursuant to this Section 1(a) and the
number of Warrant Shares represented by this Warrant submitted for exercise is
greater than the number of Warrant Shares being acquired upon an exercise, then
the Company shall as soon as practicable and in no event later than five (5)
Business Days after any exercise and at its own expense, issue a new Warrant
representing the right to purchase the number of Warrant Shares purchasable
immediately prior to such exercise under this Warrant, less the number of
Warrant Shares with respect to which this Warrant is exercised.  The
Company shall pay any and all taxes that may be payable with respect to the
issuance and delivery of Warrant Shares upon exercise of this
Warrant.

     

    (b)  Limitations on
Exercises.  (i) The Company shall not effect the exercise of
this Warrant, and the Holder shall not have the right to exercise this Warrant,
to the extent that after giving effect to such exercise, such Person (together
with such Person’s affiliates) would beneficially own in excess of 4.99% (the
“Maximum
Percentage”) of the shares of Common Stock outstanding immediately after
giving effect to such exercise.  For purposes of the foregoing
sentence, the aggregate number of shares of Common Stock beneficially owned by
such Person and its affiliates shall include the number of shares of Common
Stock issuable upon exercise of this Warrant with respect to which the
determination of such sentence is being made, but shall exclude shares of Common
Stock which would be issuable upon (A) exercise of the remaining, unexercised
portion of this Warrant beneficially owned by such Person and its affiliates and
(B) exercise or conversion of the unexercised or unconverted portion of any
other securities of the Company beneficially owned by such Person and its
affiliates (including, without limitation, any convertible notes or convertible
preferred stock or warrants) subject to a limitation on conversion or exercise
analogous to the limitation contained herein.  Except as set forth in
the preceding sentence, for purposes of this paragraph, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange
Act.  For purposes of this Warrant, in determining the number of
outstanding shares of Common Stock, the Holder may rely on the number of
outstanding shares of Common Stock as reflected in (1) the Company’s most recent
Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the
Securities and Exchange Commission, as the case may be, (2) a more recent public
announcement by the Company or (3) any other notice by the Company or the
transfer agent setting forth the number of shares of Common Stock
outstanding.  For any reason at any time, upon the written or oral
request of the Holder, where such request indicates that it is being made
pursuant to this Warrant, the Company shall within two Business Days confirm
orally and in writing to the Holder the number of shares of Common Stock then
outstanding.  In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company by the Holder and its affiliates since the date as of
which such number of outstanding shares of Common Stock was
reported.  By written notice to the Company, the Holder may increase
or decrease the Maximum Percentage to any other percentage not in excess of
4.99% specified in such notice; provided, that any
such increase will not be effective until the 61st day
after such notice is delivered to the Company.

    (ii)  This Warrant may not
be exercised to acquire Warrant Shares to the extent that when added to those
already beneficially owned by the Holder, for purposes of any shareholder rights
plan or agreement that may be adopted by the Company in the future, such Warrant
Shares would cause such Holder to acquire beneficial ownership of the percentage
of shares of the outstanding Common Stock of the Company which would make the
Holder (or any group including the Holder) an “Acquiring Person”
thereunder.

    


    (c)  Cashless
Exercise.  The Holder may, in its sole discretion, but only at
times the Registration Statement is not effective or an exemption from
registration is not available, exercise this Warrant in
whole or in part and, in lieu of making the cash payment otherwise contemplated
to be made to the Company upon such exercise in payment of the Aggregate
Exercise Price, elect instead to receive upon such exercise the “net number” of
shares of Common Stock determined according to the following formula (a “Cashless
Exercise”):

     

    (X) = Y (A-B)

                  (X)
      =

                	
                  the
      net number of Warrant Shares to be issued to the
Holder;

                
	 	 	 
	 
      	
                  (Y)
      =

                	
                  the
      number of Warrant Shares issuable upon exercise of this Warrant in
      accordance with the terms of this Warrant by means of a cash exercise
      rather than a cashless exercise;

                
	 	 	 
	 
      	
                  (A)
      =

                	
                  the
      Market Price (as defined below); and

                
	 	 	 
	 
      	
                  (B)
      =

                	
                  the
      Exercise Price of this Warrant, as adjusted from time to
    time.

                


        

      

       

    

    Solely
for the purposes of this paragraph, Market Price shall be calculated as of the
Trading Day (defined for this purpose as any day on which the NASDAQ Capital
Market, or any other national securities exchange, automated system or Over the
Counter Bulletin on which the Company’s Common Stock is then listed or admitted
to trade, is open for trading) immediately preceding the date which the Notice
of Exercise is deemed to have been sent to the Company pursuant to Section 14 hereof
(such preceding date, the “Valuation Date”). As
used herein, the phrase “Market Price” shall
mean (i) if the Warrant Shares is listed or admitted for trading on a national
securities exchange, an automated quotation system or the Over the Counter
Bulletin Board, the last reported sale price per share of the Warrant Shares on
the Valuation Date, or, in case no such reported sale takes place on such day or
is reported, then the average of the last reported per share bid and ask prices
for the Warrant Shares on such date (or if such bid and ask prices are not
available on such date, the most recent preceding date), in either case as
officially reported by such securities exchange, quotation system or Bulletin
Board on which the Common Stock is listed or admitted to trading, (ii) if not so
listed or admitted for trading, the fair market value of a share of the Warrant
Shares as determined by the Company’s board of directors in good faith, or (iii)
if such exercise is in connection with a merger or consolidation of the Company
in which the Company is not the survivor or in which the Warrant Shares are
exchanged for cash or other securities or a sale of all or substantially all of
the assets of the Company (collectively, a “Sale”), the implied
price per share of the Warrant Shares resulting from such Sale.

    For
purposes of Rule 144(d) promulgated under the Securities Act, as in effect
on the date hereof, assuming the Holder is not an affiliate of the Company, it
is intended that the Warrant Shares issued in a Cashless Exercise shall be
deemed to have been acquired by the Holder, and the holding period for the
Warrant Shares shall be deemed to have commenced, on the closing date of the
offering pursuant to which the Company was obligated to issue this
Warrant.

     

    (d)  The
stock certificate or certificates for the Warrant Shares to be delivered in
accordance with this Section 1 shall be in
such denominations as may be specified in said notice of exercise and shall be
registered in the name of the Holder or such other name or names as shall be
designated in said notice. Such certificate or certificates shall be deemed to
have been issued and the Holder or any other person so designated to be named
therein shall be deemed to have become the holder of record of such shares,
including to the extent permitted by law the right to vote such shares or to
consent or to receive notice as shareholders, as of the time said notice is
delivered to the Company as aforesaid.

     

    (e)  The
Company shall pay all expenses payable in connection with the preparation, issue
and delivery of stock certificates under this Section 1; provided, however, that the
Holder shall be responsible for all transfer taxes resulting from the fact that
any certificate issued in respect of the Warrant Shares is not in the name of
the Holder.

     

    (f)  All
Warrant Shares issuable upon the exercise of this Warrant in accordance with the
terms hereof shall be validly issued, fully paid and nonassessable, and free
from all liens and other encumbrances thereon, other than liens or other
encumbrances created by the Holder or restrictions upon transfer under federal
or state securities laws.

     

    (g)  In
no event shall the warrant be exercised for less than one whole share of
the Company except in the case of the final exercise of the warrant, and in such
event the Company shall deliver in cash to such holder an amount equal to such
fractional interest.

     

    Section
2.  Adjustment of Warrant Shares and Exercise Price.

     

    If the
Company at any time on or after the Issue Date subdivides (by any stock split,
stock dividend, recapitalization, reorganization, scheme, arrangement or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the number of Warrant Shares will be proportionately
increased and the Exercise Price in effect immediately prior to such subdivision
will be proportionately reduced. If the Company at any time on or after the
Issue Date combines (by any stock split, stock dividend, recapitalization,
reorganization, scheme, arrangement or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the number
of Warrant Shares will be proportionately decreased and the Exercise Price in
effect immediately prior to such combination will be proportionately increased.
Any adjustment under this Section 2 shall become effective at the close of
business on the date the subdivision or combination becomes
effective.

    Section
3.  Rights Upon Distribution of Assets.

     

    If the
Company shall declare or make any dividend or other distribution of its assets
or rights to acquire its assets (but not including distributions subject to
Section 4) to
the record holders of shares of Common Stock, by way of return of capital or
otherwise (including, without limitation, any distribution of cash, stock or
other securities, property or options by way of a dividend, spin off,
reclassification, corporate rearrangement, scheme of arrangement or other
similar transaction) (a “Distribution”), then
any Exercise Price in effect immediately prior to the close of business on the
record date fixed for the determination of holders of shares of Common Stock
entitled to receive the Distribution shall be reduced, effective as of the close
of business on such record date, to a price determined by multiplying such
Exercise Price by a fraction of which (i) the numerator shall be the weighted
average price of the shares of Common Stock on the Trading Day immediately
preceding such record date minus the value of the Distribution (as determined in
good faith by the Company’s Board of Directors) applicable to one share of
Common Stock, and (ii) the denominator shall be the weighted average price of
the shares of Common Stock on the Trading Day immediately preceding such record
date.

     

    Section
4.  Purchase Rights.

     

    In
addition to any adjustments pursuant to Section 2 above, if at any time prior to
the Expiration Date the Company grants, issues or sells any Options, Convertible
Securities or rights to purchase stock, warrants, securities or other property
pro rata to the record holders of shares of Common Stock (the “Purchase Rights”),
then the Holder will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which the Holder could have
acquired if the Holder had held the number of shares of Common Stock acquirable
upon complete exercise of this Warrant (without regard to any limitations on the
exercise of this Warrant) immediately before the date on which a record is taken
for the grant, issuance or sale of such Purchase Rights, or, if no such record
is taken, the date as of which the record holders of shares of Common Stock are
to be determined for the grant, issue or sale of such Purchase
Rights.

     

    Section
5.  Fundamental Transaction.

     

    Upon the
occurrence of any Fundamental Transaction, the Successor Entity shall succeed
to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Warrant referring to the “Company” shall
refer instead to the Successor Entity), and may exercise every right and power
of the Company and shall assume all of the obligations of the Company under this
Warrant with the same effect as if such Successor Entity had been named as the
Company herein.  Upon consummation of the Fundamental Transaction, the
Successor Entity shall deliver to the Holder confirmation that there shall be
issued upon exercise of this Warrant at any time after the consummation of the
Fundamental Transaction, in lieu of the shares of the Common Stock (or other
securities, cash, assets or other property purchasable upon the exercise of the
Warrant prior to such Fundamental Transaction), such shares of stock,
securities, cash, assets or any other property whatsoever (including warrants or
other purchase or subscription rights) which the Holder would have been entitled
to receive upon the happening of such Fundamental Transaction had this Warrant
been converted immediately prior to such Fundamental Transaction, as adjusted in
accordance with the provisions of this Warrant.  In addition to and
not in substitution for any other rights hereunder, prior to the consummation of
any Fundamental Transaction pursuant to which holders of shares of Common Stock
are entitled to receive securities or other assets with respect to or in
exchange for shares of Common Stock (a “Corporate Event”),
the Company shall make appropriate provision to insure that the Holder will
thereafter have the right to receive upon an exercise of this Warrant within 90
days after the consummation of the Fundamental Transaction but, in any event,
prior to the Expiration Date, in lieu of the shares of the Common Stock (or
other securities, cash, assets or other property) purchasable upon the exercise
of the Warrant prior to such Fundamental Transaction, such shares of stock,
securities, cash, assets or any other property whatsoever (including warrants or
other purchase or subscription rights) which the Holder would have been entitled
to receive upon the happening of such Fundamental Transaction had the Warrant
been exercised immediately prior to such Fundamental Transaction.  The
provisions of this Section shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied without
regard to any limitations on the exercise of this Warrant.

    Section
6.  Reservation and Authorization of Capital Stock.

     

    The
Company shall, at all times on and after the date hereof, reserve and keep
available for issuance such number of its authorized but unissued shares of
Common Stock as will be sufficient to permit the exercise in full of all
outstanding Warrants.

     

    Section
7.  Noncircumvention.

     

    The
Company hereby covenants and agrees that the Company will not, by amendment of
its Articles of Incorporation, Bylaws or through any reorganization, transfer of
assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale
of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, and will at all
times in good faith carry out all the provisions of this Warrant and take all
action as may be required to protect the rights of the
Holder.  Without limiting the generality of the foregoing, the Company
(i) shall not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, (ii) shall use all reasonable efforts to take all such actions as
may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of this Warrant and (iii) shall, so long as any of the Warrants are
outstanding, take all action necessary to reserve and keep available out of its
authorized and unissued shares of Common Stock, solely for the purpose of
effecting the exercise of the Warrants, the number of shares of Common Stock as
shall from time to time be necessary to effect the exercise of the Warrants then
outstanding (without regard to any limitations on exercise).

     

    Section
8.  Rights of Shareholders.

     

    Nothing
contained herein shall be construed to confer upon the holder of this Warrant,
as such, any of the rights of a shareholder of the Company or any right to vote
for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value or change of stock to no par value, consolidation,
merger, conveyance, or otherwise) or to receive notice of meetings, or to
receive dividends or subscription rights or otherwise until the Warrant shall
have been exercised and the certificates representing the Warrant Shares shall
have been issued, as provided herein.

    Section
9.  Stock and Warrant Books.

     

    The
Company will not at any time, except upon dissolution, liquidation or winding
up, close its stock books or warrant books so as to result in preventing or
delaying the exercise of any Warrant.

     

    Section
10.  Limitation of Liability.

     

    No
provisions hereof, in the absence of affirmative action by the Holder to
purchase Warrant Shares hereunder, shall give rise to any liability of the
Holder to pay the Exercise Price or as a shareholder of the Company (whether
such liability is asserted by the Company or creditors of the
Company).

     

    Section
11.  Transfer, Division and Combination.

     

    This
Warrant may be transferred without the written consent of the Company. Any
Warrants issued upon the transfer of this Warrant shall be numbered and shall be
registered in a Warrant Register as they are issued. The Company shall be
entitled to treat the registered holder of any Warrant on the Warrant Register
as the owner in fact thereof for all purposes and shall not be bound to
recognize any equitable or other claim to, or interest in, such Warrant on the
part of any other person, and shall not be liable for any registration of
transfer of Warrants that are registered or to be registered in the name of a
fiduciary or the nominee of a fiduciary unless made with the actual knowledge
that a fiduciary or nominee is committing a breach of trust in requesting such
registration or transfer, or with the knowledge of such facts that its
participation therein amounts to bad faith. This Warrant shall be transferable
only on the books of the Company upon delivery thereof duly endorsed by the
Holder or by his duly authorized attorney or representative, or accompanied by
proper evidence of succession, assignment, or authority to transfer. In all
cases of transfer by an attorney, executor, administrator, guardian, or other
legal representative, duly authenticated evidence of his or its authority shall
be produced. Upon any registration of transfer, the Company shall deliver a new
Warrant or Warrants to the person entitled thereto. Notwithstanding the
foregoing, the Company shall have no obligation to cause Warrants to be
transferred on its books to any person if, in the opinion of counsel to the
Company, such transfer does not comply with the provisions of the Securities Act
and the rules and regulations thereunder. This Warrant may be divided or
combined with other warrants of like tenor and representing in the aggregate a
like amount, upon presentation at the aforesaid office of the Company, together
with a written notice specifying the names and denominations in which new
Warrants are to be issued, signed by the Holder or its agent or attorney. The
Company shall pay all expenses in connection with the preparation, issue and
delivery of Warrants under this Section 11. The
Company agrees to maintain at its aforesaid office books for the registration of
the Warrants.

    Section
12.  Loss, Destruction of Warrant Certificates.

     

    Upon
receipt of evidence satisfactory to the Company of the loss, theft, destruction
or mutilation of any warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity and/or security satisfactory to the
Company or, in the case of any such mutilation, upon surrender and cancellation
of such Warrant, the Company will make and deliver, in lieu of such lost,
stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and
representing the right to purchase the same aggregate number of Warrant
Shares.

     

    Section
13.  Amendment and Waiver.

     

    Except as
otherwise provided herein, the provisions of this Warrant may be amended and the
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, if (but only if) the Company has obtained the
written consent from the majority of the holders of the Warrant Series; provided, that no
such action (other than those contemplated by Sections 3 or 5) may increase the
exercise price of this Warrant or decrease the number of shares or class of
stock obtainable upon exercise of this Warrant without the written consent of
the Holder.  No such amendment shall be effective to the extent that
it applies to less than all of the holders of the Warrant Series then
outstanding.

     

    Section
14.  Notices Generally.

     

    Any

receipt requested; (ii) by facsimile transmission with confirmation of receipt;

    Section
16.  Governing Law.

     

    This
Warrant shall be governed by and construed and enforced in accor­dance with,

    Section
17.  Dispute Resolution Regarding Exercise Price and Warrant
Shares.

     

    In the
case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the Warrant Shares, the Company shall submit the
disputed determinations or arithmetic calculations within two Business Days of
receipt of the Exercise Notice giving rise to such dispute, as the case may be,
to the Holder.  If the Holder and the Company are unable to agree upon
such determination or calculation of the Exercise Price or the Warrant Shares
within five Business Days of such disputed determination or arithmetic
calculation being submitted to the Holder, then the Company shall, within two
Business Days submit the disputed arithmetic calculation of the Warrant Shares
to the Company’s independent, outside accountant.  The Company shall
cause the accountant to perform the determinations or calculations and notify
the Company and the Holder of the results no later than ten Business Days from
the time it receives the disputed determinations or
calculations.  Such accountant’s determination or calculation shall be
binding upon all parties absent demonstrable error.  The expenses of
the accountant will be borne by the Company unless the accountant determines
that the determination of the Exercise Price or the arithmetic calculation of
the Warrant Shares by the Holder was demonstrably in error, in which case the
expenses of the accountant will be borne by the Holder.
